Owen McCormick excluded 3 East Mediterranean outliers from these Roman charts.
For some reason the charts about Bronze Age Iberians has hair colour and Y-DNA (instead of eye color). BA Iberians had about 75% of brown eyes.
The author of the charts mentioned that he only used liberian samples with Steppe autosomal DNA (hence the predominance of R1b samples).

If both eye color and hair color are very polygenic, how did they determine eye color and hair color? According to one of the eye color determinant based on DNA I am supposed to have gray eye color (my father had blue gray eyes). I, however have dark brown eyes and dark brown hair.
It is polygenic indeed, but if I'm not mistaken there is one "main switch", namely HERC2/OCA2, SNP rs12913832. If you have other blue/grey/green eye variants, but not even one of those, you are highly likely to get brown eyes.
To differentiate e.g. blue from green eyes, you need to use a polygenic score, because there is more than one allel involved. Therefore they likely did just differentiate light from dark with HERC2 would be my guess.
